Series Land Rovers have always had petrol engines as an option but from 1957 diesel engines were also offered.

Diesel engines
Diesel is pulled from the tank by a mechanical lift pump and passed through a series of filters to the injector/distributor pump. From here a controlled amount of diesel is passed to the fuel injectors in the cylinders, depending upon what load the engine is experiencing at that moment in time. The diesel enters the cylinders at very high pressure and as a fine spray.

Petrol engines
Petrol is pulled from the tank by an electrical fuel pump in Series I models and by a mechanical pump in Series II, IIA and III models. An electric pump(mounted on the dash) was an option though in the 2286cc engine. The six cylinder engine, introduced in 1967, has an electrical fuel pump.
Carburettors started as Solex and then changed to Zenith, but the 6-cylinder engine uses Stromberg or SU carburettors.
Coarse fuel filters are situated in the tank uptake pipe and fuel pump. A sediment bowl is also often an integral part of the mechanical fuel pump. Many Series Land Rover owners these days fit an aftermarket inline paper fuel filter.

The February 2013 UK homepage focuses on the mechanical fuel pump. It discusses its operation, possible problems and basic maintenance.

The March 2013 UK homepage describes where and how to check for possible fuel leaks in the fuel system of a Series Land Rover. Suggestions for temporary and permanent solutions are given where appropriate for the carburettor, engine and other parts of the fuel system.
